To calculate the percent yield, we first need to identify which is the limiting reactant and how many moles of the hydrogen can be produced from this limiting reactant.
00:11
We have amounts for both methane and water.
00:15
So we need to calculate the moles of hydrogen that can be produced from the amounts of methane and water.
00:22
Because they are both gases, we'll use the ideal gas law to calculate the moles of methane we have and the moles of water we have, and then use the stoichiometry.
00:32
To calculate the moles of hydrogen that can be produced from each of them.
00:37
The ideal gas law tells us that the pressure in atmospheres, so we'll take the pressure in tor, divided by 760 to get it into atmosphere, multiplied by the volume of methane, divided by r, divided by the temperature of methane, gives us 1 .004 moles of methane.

Because it's a 1 to 3 relationship, then we'll make three times that of hydrogen, if all of the methane is consumed...
